Abstract
This study aims to observe and compare the effects of high-viscosity bone cement versus standard bone cement on the postoperative outcomes of percutaneous vertebroplasty (PVP) in patients with Kummell disease. A retrospective analysis was conducted on 135 patients with Kummell disease who underwent PVP between January 2019 and May 2023. Patients were divided into 2 groups: the high-viscosity group (group H, 63 cases) received high-viscosity bone cement during surgery, while the standard group (group S, 72 cases) received standard bone cement. Surgery duration, bone cement volume, bone cement leakage rate, as well as preoperative and postoperative evaluations using the Visual Analogue Scale (VAS) for pain, Oswestry Disability Index (ODI), anterior vertebral height, and kyphotic Cobb angle were recorded and compared between the 2 groups. In the group H, significant improvements were observed in VAS scores, ODI, anterior vertebral height, and Cobb angle at 24 hours, 3 months, and 1 year postoperatively compared to preoperative values (P < .01). In the group S, VAS scores and ODI showed significant improvement at 24 hours, 3 months, and 1 year postoperatively (P < .01), but there were no significant differences in anterior vertebral height or Cobb angle compared to preoperative values (P > .05). Comparatively, the group H demonstrated superior outcomes in terms of bone cement volume, leakage rate, recovery of anterior vertebral height, and Cobb angle correction at 24 hours, 3 months, and 1 year postoperatively (P < .05). However, there were no significant differences between the 2 groups in terms of surgery duration, VAS scores, and ODI at the same time points (P > .05). PVP is an effective treatment for Kummell disease, providing significant pain relief and improved spinal function. The use of high-viscosity bone cement allows for greater volume infusion, better restoration of vertebral height, and correction of deformities, while also reducing the risk of cement leakage.
